Logical Fallacies — the Argument from Authority
Posted by Troythulu
This particular form of argument attempts to assert the truth of a claim by calling upon supposed — but sometimes misleading or irrelevant, sometimes even false — qualifications, virtues, and certifications of the one making the claim to ‘prove’ the claim true, irrespective of logic and real evidence. This argument in both valid and fallacious usage usually has the following format:
Person A has apparent or claimed qualifications Q. Person A says that X is true. Therefore X is true. Note that the valid form of this argument attaches the qualifier ‘probably’ to the alleged truth of claim X, since in this case the truth of the claim cannot follow necessarily or be known with certainty.
Or to put it another way…
Dr. Von Blümrich is a great rocket scientist. Dr. Von Blümrich claims that the vision described in the Biblical book of Ezekiel was that of a visitation by ancient astronauts in a rocket-powered spacecraft. Therefore, despite a complete lack of any physical evidence of a spacecraft landing in the Middle East at around that time, it must be true that Ezekiel’s vision was literally a physical event, and described an alien rocketship, not Ezekiel hallucinating out of his tree in a mystical experience.
People, I sh*t you not. Someone actually used that argument on me, and it wasn’t convincing then either…
Another example of this style of argument, used on me by someone who otherwise has the intellectual resources to know better than to commit such an obvious fallacy, is…
“Time travel is impossible, because Professor so-and-so, at such-and-such University, whom I highly respect because he’s very intelligent, said that it is…”
There is a wide variety of supposed but irrelevant virtues invoked in this form of specious argument — itself a subset of genetic fallacy – an argument that uses the origin of a claim to assert its truth — including such things as wealth, sincerity, intelligence, unconventionality, age (or youth), ancient wisdom (the Appeal to Antiquity), wide social acceptance (the Appeal to Popularity), celebrity (Appeal to Celebrity), novelty (Appeal to Novelty), beauty, strength or power, social status, subjective personal experience, quotations by someone famous taken out of context or even fabricated (Quote-Mining), purity, virginity, charity, sincerity, claims of impending acceptance (a combination of Argument from Authority & Unstated Major Premise), piety, self-assumed but unsubstantiated authority, claimed divine inspiration or origin, vague references to ‘experts,’ ‘scientists,’ ‘researchers,’ or other authorities that cannot be followed up on, and even such normally non-advantageous things as poverty and persecution. The list goes on, and some of these may even shade into other logical fallacies, but you get the idea…
In any case, this sort of argument attempts to deceive about the nature of the evidence it presents, a gambit to disguise itself as valid logic and actual evidence while not really presenting either.
This was an acceptable form of argument even in it’s fallacious form in medieval scholasticism, but we’ve moved on a bit since then, and in that usage no longer widely accepted by philosophers of science and logicians as sound reasoning.
While an Argument from Authority is always fallacious when the authority so name-dropped is considered in effect to be incontrovertibly correct, its not-so-evil mirror universe twin, an Argument by Authority, made by someone or in reference to someone whose experience, training, and other qualifications are both real and relevant to the issue being discussed, when they have a sound basis for their statements, can be a valid form of argument.
Finally, as mentioned above, this can shade into an ad Hominem along a continuum, with a fuzzy but real division between them in some arguments, in that often those people in the best position to examine the truth or falsehood of a statement just happen to be those individuals with experience, a vested interest and personal involvement in the subject at hand.

About TroythuluI seek to learn through this site and others how to better my ability as a person and my skill at using my reason and understanding to best effect. I do fractal artwork as a hobby, and I'm working to develop it to professional levels, though I've a bit to go till I reach that degree of skill! This is a crazy world we're in, but maybe I can do a little, if only that, to make it a bit more sane than it otherwise would be.
